LASTING-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 786,047, dated March 28, 1905.

Application i'iled July 14, 1900- Serial No. 23,569.

To [LIZ whom t may concern:

Re it known that I, RONALD FRANCIS Mc- FEELY, of Beverly, county of Essex, and Commonwealth of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the following, read in connection with the accompanying drawings, is a specification.

This invention relates to machines for lasting boots and shoes, and particularly to lasting-machines of the type known as the handmethod lasting-machine,an example of which is shown and fully described in United States Letters Patent No. 584,744, of June 15, 1897. In machines of this type a single pair of pincers is employed which grip the upper and are actuated to work the upper over the last, and during certain portions of the lasting operation-for example, when the toe or other curved portions of the shoe are being operated uponthe pincers are given additional movements for forming plaits in the marginal `edge of the upper to dispose of the excess of material.

The object of this invention is to provide improved mechanism for forming smooth and regular plaits in the edge of the upper.

Another object of the invention is to provide improved mechanism for imparting a yielding lateral movement to the pincers.

Other advantages of my invention Will be hereinafter pointed out.

Referring to the drawings, Figure 1 is a side elevation of a machine embodying this invention. Fig. 2 is a front elevation, partly in section, of a portion of the machine shown in Fig. 1. Figs. 3 and 4 are plan views showing details connected with Fig. 2. Figs. and '6 are detail perspective views. Fig. 7 is a section on line7 of Fig. 5. Fig. 8 is a section on line 8 of Fig. 6. Fig. 9 is a detail view showing in front elevation the pincers and upper slitting members. Fig. 10 is a plan of the parts shown in Fig. 9. Fig. 11 is a side elevation of the parts shown in Fig. 9. Fig. 12 is a longitudinal section of the parts shown in Fig. 9. Fig. 13 is a perspective view of one of the cutters detached from its ing operation.

carryingshaft. Fig. 14 is a detail view, partly in section, showing one of the cutters secured to its shaft. Fig. 15 is a section on line 15 of Fig'. 14, and Fig. 16 is a perspective view illustrating the cutter' in operation.

In the preferred embodiment of my invention herein shown the mechanism for forming plaits in the edge of the upper comprises pincers and mechanism for moving the pincers laterally and turning them, in combination with means for slitting the marginal edge of the -Lipper'.

The pincers, which comprise the members 14 and 18, are carried by bars 12 and 16, which are mounted in a carrier hereinafter described. rIhe bar 12 gives support to bar 16 and is provided with a ball-shaped end 60, socketed in a lever 62, which is tilted vertically by suitable mechanism described and shown in said Patent No. 584,744 for lifting and loweringl the pincers to carry out the operations of seizing the upper and straining it upwardly from the edge of the last. The said ball-and-socket connection allows the bar 12 to be swung forwardly and backwardly to effect movements of the pincers for 'laying the strained upper overthe inner sole and also allows the bar 12 to be swung from side to side and turned to effect movements of the pincers for twisting and plaiting the upper during portions of the last- To facilitate the carrying out of said swinging and turning movements of the pincers Without cramping the connecting mechanism, a carrier is employed, which comprises a vertical part 70, arranged in sliding engagement with the bar 12, said carrier also having' a horizontal part 71, which is supported for rocking and endwise movements in the forked end of a yoke 72, carried by an endwise-movable shaft 74. The shaft 74 is actuated by mechanism described in the patent referred to, and the endwise movements of said shaft will operate to swing the bar 12. and consequently move the pincers backwardly and forwardly over the last for placing the gripped upper over the inner sole.v

The carrier which supports the pincer-bars is actuated for moving the pincers laterally by means of a rod 78, connected at one end to l one the carrier, as shown in Fig. 2` and at its other end to mechanism which imparts a reciprocating movement thereto, said mechanism being shown and described in the patent referred to. The mechanism which reciprocates rod 78 also imparts a reciprocating movement to a link 180, connected to the lower end of lever 170. To the upper end of said lever 170 is connected a slide-bar 68, having' rack-teeth 66, which engage correspondingteeth 64, formed on the ball-shaped end 60 of the bar 12, so that whenever said slide-bar is moved the pincerbar 12 will be rotated for turning' or twisting the pincers about an axis which is approximately perpemlicular to the bottom of the shoe being lasted, and as the rod 78 and link 180 are actuated by the same mechanism the pincers are turned and moved laterally simultaneously.

Then the sides and other comparatively straight portions of a shoe are being' lasted, the pincers operate in a plane substantially perpendicular to the central longitudinal plane of the machine, and at such times the mechanism for turning the pincers and moving' them laterally is inoperative; but when the right-hand side of the toe portion is to be lasted the workman will actuate a shifting device, which causes said mechanism to become operati ve, so that at the next cycle of operations the pincers will be turned and moved laterally to the right of the central longitudinal plane of the machine into position to engage the edg'e of the upper at the right-hand side of the toe portion of the shoe, the gripping-faces of the pincers when they arrive at this position being' in approximately the same plane as the edg'e of the upper which is to be gripped. After the upper has been gripped the pincers are turned and moved laterally to the left of said central longitui'limtl plane for forming a plait, as hereinafter described. When the left-hand side of the toe portion is to be lasted, the workman will change the position of the shifting device, and thereafter while said device is in this adjusted position the receiving position of the pincers will be at the left of said central longitudinal plane and their lateral movements for forming the plaits will be from left to right. 1n the machine herein shown as embodying' my invention the shifting device is so connected to the mechanism for turning the pincers and moving them laterally that in case said shifting device is actuated at a certain time of the machines operation said shifting device will cause the pincers to be turned and moved laterally. rl `l1is, however, will not always occur, and in the following description and in the claims such expressions as means for moving the pincers laterally and turning them refer to the mechanism which the shifting device sets in operation.

The slits in the edge of the upper permit section of upper to be superimposed upon the section adjacent thereto, so that each plait comprises only two thicknesses of upper material, and the turning movement of the pincers twists the section of upper which is to be superimposed relatively to the slit formed in the marginal edge of the upper.,

Preferably said section of upper is twisted about a center located at or near the inner end of the slit in the edge of the upper, so that the plait which is formed will extend from the inner end of the slit to the edge of the upper. Accordingly there is no tendency for the upper at the edge of the shoe to` pucker or bunch up by reason of the plaits extending too far.

The cutters 52 and 48 are secured by clamping-screws 54 50 to tubular shafts 36 38, which are movably mounted in tubular boss extensions 32 34 on the pincers-bar 12. Said shafts are moved endwise in said extensions and during such` movement are given a partial rotation by means of devices 41 and 42, attached tothe bar 12 and projecting into spiral grooves or slots formed in the shafts, only one of said grooves being shown at 44 in Fig. 14. Springs 40, which are confined within the tubular shafts, rest upon the devices 41 42 and operate to hold said shafts normally elevated. rl`he arrangement of said parts is such that the cutter 48 is on one side of the pincers, and on the other side thereof is the cutter 52, the purpose of mounting a cutter on each side of the pincers being to enable slits to be formed in the edge of the upper at one side of the pincers when they are turned and moved laterally in one direction for forming plaits on one side of the toe portion of the shoe and to enable slits to be formed in the edge of the upper at the other side of the pincers when they are turned and moved laterally in the opposite direction for forming plaits on the other side of the toe portion.

The cutters normally stand above the plane of the gripping-faces of the pincers, as shown in Figs. 9, 11, and 12, and after the pincers have gripped the upper and are moving' upwardly to stretch the upper the shaft 36 or 38, depending' upon which side of the toe or other curved part is being operated upon, is moved downwardly, thereby forcing the cutter into the edge of the upper materialadjacent to the side of the pincers. In the downward movement of said cutter-shaft it is partially rotated by action of the device on the bar 12, which projects into the spiral g'roove or slot in the shaft, such partial rotation preferably taking place after the cutter has entered the edge of the upper and while it is approaching' the end of its cutting movement. By rotating the cutter during the latter portion of its downward stroke I form the inner portion of the slit by a skiving cut which leaves the two edges beveled, so that the sections of upper may readily be overlapped in IOO Y forming the inner or narrow end of the plait. Such movement of the cutter enables it to pass through the leather more easily and also causes it to bear upon the underneath section of upper at the inner end of the slit and smooth it down to receive the section which is superimposed thereon. The shaft and cutter are returned to normal position by the liftingspring' 40. Preferably the cutter is actuated for forming the slit at the same time the pincers are moving upwardly for stretching the upper, and as the upper is not stretched any after the slit has been formed all of the slits will terminate a uniform distance from the edge of the inner sole, thereby insuring uniform plaits.

In lasting the left side of the toe portion of the upper after the upper has been gripped and the cutter 52 has been actuated for forming a slit in the marginal edge thereof the pincers are moved laterally to the left of the central longitudinal plane of the machine to superimpose the slitted section of upper up'on the section at the left thereof, said superimposed section being then fastened in place. The pincers are thereafter moved back into their receiving position at the right of said central plane, and the same operations are repeated for forming the other plaits at this side of the toe portion. 'Fliese operations are reversed for the other side of the toe.

For operating the cutter-carrying shafts 36 and 38 a lever 104 is provided, said lever being loosely mounted on a rock-shaft 102, that is carried by the frame of the machine. (See Fig. 5.) A finger 110 is pivotally connected at 120 to a stud 106, which is fastened in the end of lever 104 by a bolt 108, said finger being held normally in alinement with the lever by a plunger 114, that is forced into engagement with a notch 112 in the end of finger 110 by a spring 116.

When the pincers are operating in their central position, the mechanism for turning the pincers and moving them laterally is inoperative, and the finger 110 passes between thecutter-carrying shafts 36 and 38 whenever lever 104 is depressed; but when said mechanism becomes operative the pincers are thereby turned and moved laterally into their receiving position, and the cutter -actuating mechanism then becomes operative, because one of said cutter-carrying shafts then stands in alinement with the finger 110, so that it will engage and depress it when the lever 104 is actuated.

r1`he lever 104 is provided with a buffer 103, which contacts with an adjustable stop 105, carried by the frame of the machine when the lever is in its elevated position, said lever being held normally elevated by a spring pressed plunger 104,mounted in saidlever and bearing against a stationary part of the frame, as shown in Fig. 5. The lever 104 is intermittingly depressed by means of a cam 100,

mounted on the main shaft D, said cam coperating with a wear-plate 206 on an arm 150, fixed to the rock-shaft 102. Another arm 122 is fastened to said rock-shaft and is provided with amovable plunger 128, which is adapted to engage recesses in a plate 134, carried by lever 104, so as to couple said arm and lever together, said lever being loosely mounted on the rock-shaft between the hubs of the arms 150 and 122. As the shaft 102 is rocked by means of the cam 100 the lever 104 through its connection with arm 122 will be moved downwardly. Some times it is desi rable to discontinue the operation of the slitting mechanism while the pincers continue to turn and move laterally for forming plaits, and to provide for this the connection between the arm 122 and lever 104 is made adjustable, theplate 134 in lever 104 having two recesses 130 and 132 and the plunger 128 being movably mounted in the arm 122, so that it can be moved into engagement with either recess. Preferably said plunger 128 is mounted in a sleeve 124, carried by the arm, and is provided at its outer end with a cam-faced collar 138. A spring 140, mounted in said sleeve, moves the plunger outwardly so that it will engage one of the recesses in the plate 134, and a camfaced lever 126, rotatably mounted on the sleeve 124, cooperates with the cam-face on collar 138 for retracting said plunger. As shown in Figs. 6 and 8, when the plunger is in engagement with recess 130 the wear-plate on arm 150 will be held out of the path of movement of the cam 100; but fwhen the plunger is in engagement with recess 132, as shown in Fig. 5, said wear-plate will be in position to be engaged at each rotation of the cam and the shaft 102 will be intermittingly rocked and the lever 104 depressed.

1t will be understood from the foregoing description that while the pincers are operating in their central position for lasting the straight portions of the shoe the cutter-actuating mechanism is inoperative, as the finger 110 passes between the cutter-carrying shafts and does not impart movement thereto; but when the operator moves the device which causes the pincers turning and moving mechanism to become operative and the pincers are thereby moved into either of their lateral positions the cutter-actuating mechanism will then become operative, as the finger 110 will then be in alinement with one of the cuttercarrying shafts, so that a downward movement of lever 104 will carry said finger into engagement with said shaft and cause the cutter to slit the edge of the upper. If the pincers should be moved laterally while the finger 110 is standing between the cuttercarrying shafts, said finger will swing on its pivot 120, thereby preventing breakage -of parts.

In further carrying out my invention I have provided a novel yielding connection, herein IOO shown as interposed between the pincers-carl the pineers.

rier and the actuating-rod 78, for moving' the pineers laterally. By means of this novel connection the movements of the pineers laterally in either direction may be effected yieldingl y th rough a single spring. Referring' to Fig. 2, the horizontal part 71 of the carrier has a central longitudinal chamber in which is slidingly mounted a plung'er 80, having a shoulder 81 in juxtarelation with one end of part 71. Said part 8O has a longitudinal eentral opening or chamber 82, having threaded in itsouter end a nut 84, provided with a bore for the rod 86, said rod passing loosely through said bore and being' provided at its inner end with a head 90 in sliding engagement with plunger 80. In said chamber 82 is a spring 88, surrounding rod 86, the ends of said spring engaging the nut 84 and a shoulder 92 on the head of said rod. Fixed on the outermost end of rod 86 is a disk 96 in juxtarelation with the end of the horizontal part 71 ot' the carrier. A socket formed between the plunger and the head 90 of rod 86 gives place for the ball end 94 of the actuating-rod 78. The relative arrangement of said mechanism is such that the disk 96 and shoulder 81 rest normally against the ends of the horizontal part 71 of the carrier. While in this position bar 12 is approximately perpendicular and may be moved for causing the pineers to grip, strain, and place the upper over the inner sole along the sides of the last and places where no plaiting of the upper or superimposingl of the slitted parts thereof is desired, and consequently no turning or moving of the pineers laterally is needed.

It will be understood from the above description that moving the rod 78 cndwise in one direction causes the shoulder 92 of rod 86 to move against the tension of spring 88, whereupon said spring yieldingly transmits the movement oi' said rod to nut 84, and consequently to the plunger 8O and horizontal part 71 of the carrier, for swinging the bar 12 with a yielding' tension laterally to one side of the centrallongitudinal plane of the machine, as is required in order to move the pineers to plait or superimpose the slitted parts of the upper along one side of the shoe-toe. By moving' the rod 78, and consequently the plunger 80, from their normal position endwise in the opposite direction the nut 84 is made to move against the tension of said spring 88, whereupon said spring yieldingly transmits the movement ot' said rod to rod 86 and to the disk 96 and horizontal part 71 for swinging the bar 12 with a yielding tension laterally to the other side, as is required for moving' the pineers to plait or superimpose the slitted parts of the upper along the other side ot' the toe of the shoe. It is to be observed that a single spring` 88 is employed, which insures auniformly-yielding tension to 1t will also be observed that the force required to swing the bar 12 to one side is exerted upon one end ol the spring 88 and the force required to swing the bar 12 to the other side is exerted upon the other end ot' the spring 88. rlhe tension of said spring' may be vari-ed by adjusting the nut 84. The construction embodyingthis feature otl my invention is not only more satisfactory in operation than mechanisms heretofore used, but it is also much more economical, as it is simpler and comprises fewer parts.

rl`he pineers herein shown comprise the member 14, rigidly connected to the bar 12, and the member 18, pivotally connected to the bar 16, which is supported by the bar 12.

The pineers are opened by the uplifting endwise movement of bar 16 and are closed together by reversely moving said bar. This operation is effected by mechanism shown and described in the patent referred to.

In the member 18 is a plunger 20, having one end on the bar 16 and its other end on a spring 22, so that during the opening otl the pincer members 14 18 the plunger will be actuated for swinging the member 18 outwardly on pivot 24. Said member 18 has a projection 26, provided with a cam-face 28 for engaging a roll 8O on bar 14, so that duringthe closingtogether movement of the pincer members the member 18 will be swung inwardly to the proper alinement for closing onto the member 14, as indicated in dotted lines in Fig. 12. This swinging action of the member 18 insures movement thereoi` outwardly to a desirable position beyond the edge ot' the shoe-upper material placed against the member 14 and then causes said member 18 to move to the gripping position withou crushing the gripped material.
